چکیده
Sulfur is one of the most common impurities in crude oil. Removing sulfur from gas or liquid fuels is one of the most important tasks of the oil refining industry [۱] . This research focuses on the surface absorption phenomenon, which involves removing organic sulfur compounds from oil cuttings through physical and chemical processes [۲] . Natural kaolin is being used in this study. To improve its efficiency, the kaolin needs to be modified first. Acid modification significantly alters the surface properties. Furthermore, calcination activates the kaolin. To achieve this, we first acid wash and then calcine it. In the next step, it is loaded with Cu۲+ and Ni۲+ metals [۳] . We are examining various parameters of the removal process and using experimental design methods to determine the optimal reaction conditions. This includes studying different absorption techniques, such as Freundlich and Langmuir methods, to determine reaction kinetics and the porous materials obtained in the desulfurization process. We are also investigating the substrates and the impact of various parameters, including the loading of metals, time, temperature, concentration, and pH [۴] . Additionally, the effects of substrates and various parameters such as loading of metals, time, temperature, concentration, and pH are being investigated .کلیدواژه ها

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
